I just got one from Ken as an early anniversary present from the lovely wife.

(She's bought me at least 3 things now from Evoluzione..) Mental note - she's wife #3, but I'm thinking this one's a keeper...

It came with 5 shims - I'm an aggressive rider - how many do I need?​


Do I need to put the bike on the stand or anything to get the old torque
arm off?


Thanks in advance guys...

Try all five and work it "down" from there. My bet is that you end up keeping at least four if you're aggressive.

The rear wheel needs to be weightless in order to remove your OEM torque arm, so yes a stand is required. I'm quite sure if you visit Ken's website there will be full instructions on the re and re in PDF format.

Your wife rocks. Happy Fathers Day.

Thanks...why the odd number of shims? Should one end have more than the other and if so, which end?

I also noticed that the two allen bolts that secure the arm to the frame are different lengths - the stock bolts are the same length?

I plan to install it today and take it out for a test ride afterwards...

I'll post the results.

After speaking with Ken, I went with all 5 shims...

Holy shit Batman - who would have thought 15 mm makes a difference?

My bike has been transfomed - this thing goes around curves like it's on rails now.

Huge difference!

I'm in love with this bike all over again.

Each shim is 3 mm , so 15 mm total and wow...what a difference in handling.

If you live to ride the twisties like I do, then it's a no brainer - thank me afterwards!
I wanted it cause I thought it looked good, but it actually works and works well.

actually, rear ride increases roughly 1/2 of shim thickness (15mm in shims gives ~8mm in ride height).

2 things,

does this mean that parts will not drag as readily, & does it help the k12r as well?...if so i am going to get this set up!

If there's 8mm lift at the back end there will be less than that at the pegs. Hard to see how maybe 5mm - 6mm at the pegs would make a big difference to the lean angle limits - maybe a degree or two at the most. Lifting the entire rear of the bike with this mod shifts the weight bias a little further forward, probably changes the CoG braking moment a touch and more importantly it alters the castor effect ? on the front wheel to a more "sensitive" angle of response. All intended to achieve "quicker" steering as a prime objective. Any improved clearance issues would most likely be minimal if not inconsequential.

Any further feedback on handling since the initial fitting. Is it any easier to drop into curves and change line once you are in a corner ? How about heavy braking - is it "skittish" or light around the rear when braking into a corner.

And...is it a little "busier" in a straight line?

Doug,

I had a chance to study how it works when I installed it. If anything, I think the ride has improved.

The way it looks to me, the torque arm actually pushes the rear tire down, therefore increasing the ride height slightly by 8mm. Because it slightly changes the angle, more weight gets transferred to the front tire when entering curves, so it feels real planted and I usually keeps my hands real loose and just steer with the rear tire using body position. Just shifting the body poistion to the left/right makes the bike just fall right in. Love the handling on the bike - BMW really did well here.

The "turn in" improvement for me was dramatic...I used all 5 shims - 2 up front and 3 in the rear.

Best mod for me so far...

One thing to note - the bracket for the ESA wires really does not fit the new torque arm, so I ditched it and just used a small tye wrap on the front eye of the torque arm, just to keep it in place.


You need to get one - you'll love it.

Lenz - I've noticed no difference in braking - I usually keep the rear brake pedal covered with my foot in case I need to trail brake or shed a little speed.
It's more forgiving now if you don't set your line up quite right, as you can make adjustments easier and with less effort.

Hey Sportrider, where can I find a picture of this thing? Would simply like to see the visual differences, if any, from the stock piece. Thanks.

Thanks. The question that I have is this, are the shims necessary or is it just additional materials to adjust/customize the ride height?

Well, after a couple of weeks, my chicken strips are now almost gone.

The FRONT ones!:D

I've noticed a little skipping on the rear tire - seems like it just happens right when I enter the apex, but it's no biggie.


Still, best mod yet - most positive effect.

Motorcyclist had a review of Evoluzione's K1200S and they glowed about the Adjustable Torque Arm. They basically said that everyone should go out and buy one because it makes the bike that much better.

I rode my buddy's 2003 GSXR 1000 yesterday and it was evident that his bike was much easier to tip in and transition than the K1200R. Of course I already knew that, it just confirmed it again and riding the bikes back to back you really notice.
